Do you have the corresponding (cython) library
SAGE_ROOT/local/lib/python3.5/site-packages/sage/misc/lazy_import.so
If so could you try (inside a python3 shell)
import sage.misc.lazy_import
that should give you a more precise error.

Indeed, could you try
$ sage -sh
(sage-sh) $ python3
>>> import sage.all

Hello,
I get nothing from "ls local/lib/python2.7/site-packages/sa*"
and what looks like a correct full sage
in local/lib/python3.5/site-packages/sage
The problem may come from "./sage" calling a python2.7 version ?

Hi Frédéric,
Can you check what are inside local/lib/python3.5/site-packages/sage
SAGE_ROOT/local/lib/python2.7/site-packages/sage

Dear all,
I just managed (using tricks to avoid a few remaining issues in
cythonization and packages) to get make succeed in building sage with
SAGE_PYTHON3=yes
Sadly, but not unexpectedly, sage then crashes at startup. Apparently,
it
cannot not find/import any cython extension..
